Desktop won't fully wake up on keyboard/mouse signal
Hi,
I'm having an aggravating problem with my old Inspiron 545 desktop. Lately my machine won't wake up properly from either regular or hybrid sleep. When the PC goes to sleep, the power button changes to an amber color from its usual white. When I try to wake the machine with the keyboard or mouse, the PC does seem to respond - the power button turns white, and I can hear fans start back up - but the machine does not fully turn back on.
I can get the machine to wake back up, but only if I cycle the power button to turn the PC off and back on again. At that point the computer will wake up from its prior state IF it was in a hybrid sleep mode before.
I've run a lot of diagnostics from the Dell support site, to no effect. I've tried running powercfg a few times, but no joy. I've also poked around the Device Manager but don't really get what I'm looking at. Any suggestions on what to check next would be appreciated.
My specific questions:
- Shouldn't the PC wake fully from the keyboard or mouse from hybrid sleep?
- What is happening when the PC responds from the keyboard but doesn't seem to fully wake up?
PC: Inspiron 545
OS: Windows 7, 64-bit

Hi J-locker,
To me, all indications are the system is waking up but with no display. Are you using integrated video or an add-on card?

I have a Radeon HD 4650 card. I checked and the drivers are up to date, along with my BIOS.

Please understand that sleep problems are fairly common and can take a fair bit or trial and error. I'll refer you to this article for some ideas. The first thing to check is event viewer.

Thus far I'm still struggling to find the cause.
One additional thing I've noticed is that pushing the power button does the same thing as hitting the keyboard or moving the mouse as I attempt to wake the computer: the button changes from amber to white, the fans come on, etc., but the PC does not wake up. Also, when I do this, the event is not captured in the Event Logs. So I'm now looking for a detailed explanation as to what happens when the PC wakes from sleep, because the issue happens after the waking process starts but before it is recorded in the Event Logs.
DISPLAY ISSUES: My display drivers are up-to-date. I uninstalled my display drivers and then installed them straight from the AMD website. I also no longer have the problem printing from IE11, which may or may not have been related to the display drivers.

You might consider restoring the factory hard drive image. I know it sounds a bit extreme but there's almost no way of telling what little tweak or major update might be causing the problem. A factory reset is quick and is very likely to solve the problem.

Finally solved the problem. After a lot of struggle with this, a couple days ago, my computer wouldn't turn on at all. Long story short, the power supply had given up the ghost. Got it replaced, and now everything - including the sleep functionality - works fine.
Guessing that one of the rails wouldn't power up fast or clean enough to allow the wake functionality to work properly.
